| Abstract: | Objective] The aim was to determine the trace mercury,arsenic and bismuth in beneficial traditional Chinese medicines samples rapidly and easily.Method]A method for determination of trace mercury,arsenic and bismuth in beneficial traditional Chinese medicines samples by a hydride generation atomic fluorescence spectrometry has been developed.Result] By using wet digestion and NH2CNNH2-KBH4-HCl system,under the optimum conditions,the detection limit were as follows: Hg of 0.15 μg/L,As of 0.18 μg/L and Bi of 0.12 μg/L respectively.The linear ranges of determination were as follows: Hg of 0-25.0 μg/L,As of 0120.0 μg/L and Bi of 0-20.0 μg/L respectively.The recovery was in the range of 96.5%-104.5%.Conclusion] The method was simple,accurate,rapid and convenient with satisfactory results. |
